    摘要： A system and method thereof are provided for multi-stage processing of one or more precursor compounds into a battery material. The system includes a mist generator, a drying chamber, one or more gas-solid separators, and one or more in-line reaction modules comprised of one or more gas-solid feeders, one or more gas-solid separators, and one or more reactors. Various gas-solid mixtures are formed within the internal plenums of the drying chamber, the gas-solid feeders, and the reactors. In addition, heated air or gas is served as the energy source within the processing system and as the gas source for forming the gas-solid mixtures to facilitate reaction rate and uniformity of the reactions therein. Precursor compounds are continuously delivered into the processing system and processed in-line through the internal plenums of the drying chamber and the reaction modules into final reaction particles useful as a battery material.

    摘要： The present invention relates to silicon-compound-coated fine metal particles, with which surfaces of fine metal particles, composed of at least one type of metal element or metalloid element, are at least partially coated with a silicon compound and a ratio of Si—OH bonds contained in the silicon-compound-coated fine metal particles is controlled to be 0.1% or more and 70% or less. By the present invention, silicon-compound-coated fine metal particles that are controlled in dispersibility and other properties can be provided by controlling the ratio of Si—OH bonds or the ratio of Si—OH bonds/Si—O bonds contained in the silicon-compound-coated fine metal particles. By controlling the ratio of Si—OH bonds or the ratio of Si—OH bonds/Si—O bonds, a composition that is more appropriate for diversifying applications and targeted properties of silicon-compound-coated fine metal particles than was conventionally possible can be designed easily.

    摘要： A method of manufacture of high-solids hydroxide slurries from caustic calcined carbonate powder is described, whereby the properties of the slurry are its low resistance to shear thinning to facilitate transport, a high stability for transport and storage, ease of reconstitution after long periods of storage, and, as required, a high concentration of chemically reactive species at the particle surface. The method achieves these specifications by mixing caustic calcined carbonate or hydroxide powder with water in an insulated reactor vessel, and agitating the slurry sufficiently such that the hydration reaction causes the water to spontaneously boil, such that the remaining hydration proceeds spontaneously under the fixed conditions of boiling through the water loss. The mixing process is preferably carried out by a shear pump. A viscosity modifier, such as acetic acid, is used to thin the slurry to enable the mixing system to maintain uniform mixing. The reaction is terminated when the boiling has spontaneously ceased and the temperature has spontaneously dropped to a set point though the reactor heat losses, where the processing time is sufficiently long that the slurry meets the desired specifications.
